WebMar 1, 2015 · To find the y-intercept (b), you need to set x to one of the x values and y to one if the y values and solve: y=mx+b b=y-mx. The function could look like this: m=getSlope (x1,y1,x2,y2) b=y1-m*x1 return b. The coordinates of the point would be (0,b), so you can return that instead if you want. Share. Improve this answer.
